Normally forced to stand beneath me, my little sister undergoes a strange transformation when our parents ask her to "take care of things while we're away." Suddenly acting responsible, she starts behaving like a mother despite being younger—helping with housework, becoming gentle toward me, as if a sudden change has come over her. Her style changes too, wearing sexy clothes that reveal her cleavage, openly flaunting her eroticism, as though she's rapidly maturing into a woman. Seeing her like this, I involuntarily get an erection. She looks at me, sighing "Such a troublesome big brother," pretending to be exasperated while secretly thrilled inside. Then, as if noticing my arousal, she clings to my cock hungrily, rubbing against it. Her actions deeply stir my emotions.
